在windows 、linux�?��L��CI默认url中的index.php处理�Ҏ��

Wed, 25 Sep 2013 04:43:00 GMT

为美观一些，��L��CI默认url中的index.php处理�Ҏ��:一个是在linux里面一个是�?strong style="color: white; background-color: #880000;">windows

里面配置环境
一》在linux里面讄��
1.打开apache的配�|�文�Ӟ��conf/httpd.conf �Q?/p>

LoadModule rewrite_module modules/mod_rewrite.so�Q�把该行前的#��L���?br />搜烦 AllowOverride None�Q�配�|�文件中有多处）�Q�看注释信息�Q�将相关.htaccess的该行信息改为AllowOverride All。【其实apache 默认的都已经打开的�?/p>

2.�?strong style="color: black; background-color: #ffff66;">CI的根目录下，卛_��index.php�Q�system的同�U�目录下�Q�徏�?htaccess�Q�直接徏立该文�g名不会成功，可以先徏立记事本文�g�Q�另存�ؓ该名的文件即可。内容如下（CI手册上也有介�l�）�Q?br />RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]
如果文�g不是在www的根目录下，例如是：http://localhost/nianyi_2011/index.php,�W�三�?/p>

需要改写�ؓRewriteRule ^(.*)$ /nianyi_2011/index.php/$1 [L]
另外�Q�如果你的网站的根目录下面还有其他的文�g夹，例：js�Q�css�Q�images�Q�config�{�等文�g夹，�q�需要过滤除去，�W�二行需要改写�ؓ�Q?br />RewriteCond $1 !^index\.php|images|js|css|config|robots\.txt)�?br />3.��?strong style="color: black; background-color: #ffff66;">CI中配�|�文�Ӟ��application/config/config.php�Q�中$config['index_page'] ="index.php";改写�?config['index_page'] = "";
4.ok�Q�完成。还要记得重启apache�?/p>

二》在windows里面开�?/p>

以上的配�|�在windows上面是不起�Q何作用的�Q�所以我们在windows里面需要设�|�我们的apache的虚拟主机，在apache里面扑ֈ�Apache-20\conf\extra\httpd-vhosts.conf �q�个文�g【我用的是服务是PHPnow�Q�很多的人用wamp】，同样扑ֈ�此文�Ӟ��在里面修改，例：
#http://www.PHPnow.org
# filename: httpd-vhosts.conf

    AllowOverride All
    Order allow,deny
    Allow from all

NameVirtualHost *

    DocumentRoot ../htdocs
    ServerName default:80
    ErrorLog logs/default-error_log

修改成：
#http://www.PHPnow.org
# filename: httpd-vhosts.conf

    RewriteEngine on
    RewriteCond $1 !^(index\.php|images|js|css|config|robots\.txt)
    RewriteRule ^(.*)$ /index.php/$1 [L]
    AllowOverride All
    Order allow,deny
    Allow from all

NameVirtualHost *

    DocumentRoot ../htdocs
    ServerName default:80
    ErrorLog logs/default-error_log

也就是把路由写到�q�里面来。记得重新启动服务�?/p>

�l�箋修改你的配置文�g�Q?br />$config['enable_query_strings'] = true
$config['controller_trigger'] = 'c';
$config['function_trigger'] = 'm';
�?config['enable_query_strings'] 修改�?false �q�样��关闭了查询字符串�Ş�?URL

现在你的文�g的�\径就可以写得了，例如�Q?a href="http://localhost/nianyi_2011/user/user_point" style="color: #3fa7cb;">http://localhost/nianyi_2011/user/user_point

��q��当于先前没有配置的�\由：http://localhost/nianyi_2011/index.php?c=user&m=user_point同样如果后面有参数的话，只用往后一�ơ篏加就好的了�?/p>

��h��意：有时候我们这样写之后样式文�g加蝲�q�来会有问题�Q�找不到js css images�{�等目录�Q�我们可以配�|�文件config.php里面讄��$config['base_url'] = 'http://localhost/2011_11_cms/';站点的目录，接着我们在view模板文�g之间��d��Q�这样就能加载其他的文�g的了
